STRIP FOR MAKING ANTIFEIGTION BEARING-ROLES.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed October 18, 1909. Serial No. 528,284.

To'alZ whom it may concern:

Be it known that I, CHARLES S. Loonwoon, a citizen of the United States, residing at 289 Market street, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Strips for Making--Antifrictio11 Bearing-Rolls, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. J

This invention relates to a strip of particular character adapted for making spirally wound rolls with channels extending across the width of the separate'coils.

The invention consists of a fiat strip of greater width than thickness having one of its-broader sidesentirely flat and the op posite. side provided with a succession of uniformly spaced transverse notches or ooves. The object of this construction for the strip is to with channelsextended across the surface of the coils to facilitate the distribution of oil over the journal and easing of the roller hearing, as the rolls revolve'therein.

journal.

The s iral interspace between thesuccessive coi s operates to carry the lubricant toward one end of the journal and the notches formed transversely in the strip are readily dis osed at an inclination opposite" to that of t e spiral interspace, and each of such notches thus operates independently to shift the oil toward the other end of the Rolls having such notches in the strip thus promote'the distribution of oil in all parts of the journal.

The invention .will be understood by reference to the annexed drawing, in which- Figure 1 is "a longitudinal section of a casing with a set of rolls therein embodying the invention;. Fig. 2 is a perspective View of one ofthe rolls detached from the bearing; Fig. 3 is a plan of the strip for making such a roll; Fig. 4 is an. edge view of the same, and Fig. 5 a cross section on line 5-5 stri furnish the roll when finishedupon the mandrel whereo n it is wound to form an anti-friction roll, while the notches he upon the outer side of the strip and in the bearing surface of the roll. This strip when wound upon a mandrel to form an antifr1ction' roll exhibits channels which extend only across the width of one coil, as itis in PI'flCtlCGlHlPOSSlblG to so space the grooves upon the strip that the grooves will coincide or form continuous channels when the is wound into a roll.

T e grooves are shown extended obliquely across the strip, but the angle of the groove to the strip is immaterial and may be varied in making the strip so as to reduce the desired effect in shifting the o longitudinally of the bearing. This device adds nothing a it greatly promotes the uniform lubrication of the bearing.

It has been proposed heretofore to.cut a continuous spiral groove obliquely across the coils of a previously wound roll at an inclination opposite to 'thatof the interspace between the coils; but the cutting of such a material to thecost of construction, while groove is very expensive and troublesome,

whereas the forming of the transverse grooves nthe strip beforeit is wound into coils 1s effected in the rolling of the strip without any perceptible expense. The coils themselves and their interspace 0 shown 1n the drawing, have a right hand inclination as the coilsare wound right hand, and the grooves or channels 5 are so disposed to the axis of the strip as to give Klze channels 6 a left hand inclination upon th finished roll, opposite to that of the coils themselves;

but if the strip were intendedto he used for left hand coils, the grooves I) would be reversely inclined to the axis of the strip. It.

-is therefore understood that the grooves b may be formed upon the strip at any desired inclination, but especially such as will form channels opposed to the interspace between the coils whenwound.

I disclaim the forming of a continuous channel upon the surface of a s irally wound roll, as such a channel can on y be formed by cutting the metal from the roll after it is Wound; whereas the grooves in my strip are formed before it is wound and cannot form a continuous channel upon a cylindrical roll.

I am aware that wires and flat stri s have been crimped in various processes 0 manuto the curvature of the mandrel.

facture whereby the strip or rod is indented upon one side and a corresponding pro ection formed upon the other side; but a stri having such rojections could not be use in winding a helical roll, as thevpro ect1ons would interfere with the uniform bending of the strip to the surface of the mandre and would cause distortions of form in the outer side of the roll. My strip requires one side flat, so that it can be readily conform What I claim and desire to secure'by Let:

ters Patent is:

wound rolls with transverse notches upon the surface of the. coils.

2. As a new article of manufacture, a rectangular stri of greater breadth than thickness for m ing spirally wound rolls, the strip having one of its broader sides flat and the op oslte side provided with a succession of um ormly s aced transverse notches u on 1ts surface, suc strip being ada ted to wind with its flat side .u on a man rel, and the notches disposed ob iquely to the axis of the stri to form grooves oblique to the edges fut e coils when wound into a cylindrical ro In testimony whereof I have hereunto set my hand 1n the presence of two subscribing witnesses.
